Too much dandelion greens?

[canary3000]

I have a canary sitting on the bottom of the cage, eating a bit and is more recluse. A day earlier I provided pesticide free dandelion leaves. Wondering if maybe he has an upset stomach. My other canaries are fine, though they did poop an enormous amount! I will lay off the greens for a while and provide protein. The sick bird is eating the mashed egg and sipping water. But it does not want to fly. Hopefully it recovers!

A sudden change in diet isn't good. That said, I put as much greens into a cage as the bird will eat. I've never seen a Canary eat too much greens.
